Instructions for Using Zero Custom Mutators

Overview

Zero Custom Mutators provide a powerful mechanism for defining data write operations beyond simple CRUD. They allow you to embed arbitrary code within your write logic, running both client-side for optimistic updates and server-side for authority and complex operations.

Key Concepts:

• Arbitrary Code: Mutators are functions, enabling complex validation, permissions, calling external services (like LLMs or sending emails), calling queue, etc.
• Client-Side Execution: Mutators run immediately on the client for instant UI feedback.
